SELF-MEASURING VESSEL.

SPECIFICATION forming part of Letters Patent No. 564,383, dated July 21,1896.

Application filed October 11. 1895. Serial 115,555,372. ct) model.)

To all whom, it may concern:

Be it known that we, CHARLES F. LEWIS and JULIAN W. CLARK, citizens ofthe United States, residing at Russell, in the county of Warren andState of Pennsylvania, have invented certain new and useful Improvementsin Self-Measuring Vessels; and we do declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to certain new and useful improvements inmeasuring devices for oil-tanks, and especially to a construction ofself-measuring vessels held within an inclosure having a singlesupply-pipe leading from an oil-tank and having a valved connection witha series of measures, whereby one vessel may be emptied by opening onevalve, or the whole series of vessels, or a certain set of measures, maybe emptied by the operation of a single valve.

To these ends and to such others as the invention may pertain, the sameconsists, further, in the novel construction, combination, andadaptation of the parts as will be hereinafter more clearly set forth,and then defined in the appended claim.

We clearly illustrate our invention in the accompanying drawings, which,with the letters of reference marked thereon, form a part of thisspecification, and in which drawings similar letters of referenceindicate like parts throughout the several views, in which- Figure 1 isa vertical longitudinal sectional view, parts in elevation, of ourinvention, showing an oil-tank and receptacle beneath containing themeasuring apparatus. Fig. 2 is a section on line 00 x of Fig. 1. Fig. 3is a front elevation of the case showing the handles for operating andFig. 4 a longitudinal section of one of the three-way valves.-

Reference now being had to the details of the drawings by letter, Adesignates an oiltank mounted on suitable supporting-legs B, and 0, cl,e, f, and g are measuring-vessels mounted on a pipe G by suitableunions, and H is a supply-pipe leading from the oil-tank to the pipes G,and H are valves located at such intervals in the pipe Gthat thecontents of one measuring-vessel may be drawn oif without affecting thecontents of the others, or all of the vessels may be drawnoffbyopcrating a single valve.

Leading ofi from the pipe G from each valve are the pipes K, which emptyinto a common pipe M, which carries the contents of the vessels to theoutside of the inclosure, where it may be conducted into a receptacle.Each valve is provided with a lever N, to the end of which is connecteda rod 0, running to the outside of the inclosure, and has suitableknobs, as Q, secured at the end of each.

S are vent-tubes extending from the upper end of each measuring-vesselup through the oil-tank and opening in the space above the oil.

The operation of the device is as follows: The measuring-vessels shownin the drawings, being in connection with the supplytank, are kept fullwhen the valves are in position shown in Fig. 1, and when it is desiredto empty the contents of the vessel the farthest to the right, the valvenearest to the outlet of said vessel is turned so as to shut off thesupply of oil, and at the same time allow the contents of the vessel torun off through the discharge-pipe, after which the valve is opened orcommunication again had with the supply-pipe by simply pushing on therod connected with said valve, and when it is desired to empty thecontents of two vessels, the valve second from the right is turned so asto allow the contents of the two vessels to the right to :escape throughthe discharge-pipe, and when it is desired to empty three vessels thethird valve is operated in a like manner, 850.

Although we have shown but five measuring-vessels in use in connectionwith our apparatus, as shown in the accompanying drawings, we do notlimit ourselves to the use of any particular number of such vessels, asit is at once evidentthat the number may be varied as desired, or tomeet the requirements for which the apparatus is to be used.

An essential feature of the invention re- 10o sides in the peculiar formof the measuringvessels, which, as will be seen upon reference to thedrawings, are at both their upper and lower ends provided with conicalextensions,

the ventilating air-pipe S leading upward from the apex of the upper endand the outlet-pipe being connected at the apex of the lower end. Bythis construction all of the air contained within the measure ispermitted to escape and the complete filling of the me asurc with oil orother liquid contained within the tank is at all times assured, whilethe outlet-pipe being connected at the apex of the lower end assures thecomplete drainage of the vessel when the outlet-valve is opened.

Having thus described our invention, what we claim to be new, and desireto secure by Letters Patent, is

Ina self-measuring vessel, the combination with the supply-tank, aseries of measuringreceptacles mounted on pipes having connection withunions, three-way globe-valves i11- terposed between the said unions,vents S extending from theupper ends of the said measuring-receptaclesthrough the supply-tank and opening near the upper portion of thesupply-tank, of the discharge-pipes K and M communicating with the saidvalves, of the series of rods 0 disposed in a horizontal plane and eachhaving connection with a valve-lever on the t11ree-way-valve stems, theforward ends of the said rods supported in apertures in the wall 15, andprovided with pullingknobs Q all substantially as shown and described.

In testimony whereof we ailix our signatures in presence of twowitnesses.
